To all whom it may concern i r L Be. itknown that I,.WILLIAM S. ELLIOTT, a resident of Pittsburgh, Allegheny county, Pennsylvania, haveinvented a new and useful Improvement in Heaters, of which the j 1 following isa full, clear, and exact description, referenceibeing had to, the accompany ing drawings, forming part of this specifiu action of" exhauststeam, although it may becation, in which 7 Figure l is a vertical section ofone form of heater embodying my invention; Fig. 2 is a s'ection taken on the line II fII of Fig. 1'; and Fig. 3 is a view similarto Fig. 2 but illustrating a modification of-rthe invention.

My inventionhas relation to the class of heaters, and more especially to feed water heaters, in which feed Wateris heated by the usedforother purposes. l

The objectof my invention is to provide a heater of this character having a simple and eflicie'nt means whereby. the pressure of steam within the heating chamber may be automatically maintained" at the desired de gree at all times; also to provide means for purifying the steam entering the heater, and also the steam which enters. the heating system to which the heater maybe connected. In this case, the automatic pressure controlling means for maintaining the desired degree of pressure within the heating chamher also acts to maintain the same degree of pressure within the heating system. A further object is to provide the con trolling means for both the heater and the heating system as a partof the heater, thereby simplifying the apparatus and reducing thecost. ofits manufacture. w

Referring. first to Figs. 1 and 2, the nu meral 2 designates the body of the heater within the upper portion of which is located asuitable water distributer 3, and pans or distributing plates 4, water being admitted to the distributer 3 through the connection indicated at 5. 6 designates the steam inlet connection for the heater,.this connection being preferably formed asa'separate casting, which is bolted to the body 2 over the inlet opening 7 thereof, the latter being-provided'with the valve-seating member 8. 9

is a combined valve and oil-separating, plate,

which controls the opening 7, and which is carried'by a shaft 10 extending through the heating chamber and provided with a bearing 11 at one end in the valve seating mem ber 8,.and with a suitable bearing 12 in the opposite wall of the heater, through which it projects, being provided with a hand wheel 13, or other suitable operating device at its outer end. The shaft 10 also has an intermediate support at 14. The face of the valve plate 9, which is opposed to the entering steam, is preferably provided with a plurality of corrugations or projections 15, in order to more effectively act as a separator for the oil contained in the entering steam. In order to more effectively support the valve and separator plate, which is of relatively large diameter, and which is subject.

to the impact of the entering steam, I pro vide the supporting" and guiding bolts 16, which are carried by the body portion 2, and which extend inwardly through openings in the valve plate, their inner ends being provided with suitable heads which act as stops for the valve in its unseating movements The steam inlet connection 6 is alsoprovided with relief port 17, which is controlled by a valve 17 seated within a chamber 18' forming an extension of the member 6, and which chamber communicates with the atmosphere or any otherdesired point through the opening 19. The valve 17 is carried by the stem 20, having the guides 21 and 22, and collars 23, the latter being engaged by a crank arm 24 on ashaft 25 journaled in the walls of the extension, and having an adjustable counterweighted arm 26. I preferably. also attach to the arm 26 the dash pot device, indicated at 27, to prevent chatter or slamming of the valve 17 Should there be an excess of steam pressure inthe exhaust line to which the inlet connection 6 is attached, and which would thereby create an excess pressure within the heater, the valve 17 (whichby adjustment of the counter-weighted arm may be set to open at any desired pressure), will unseat, and thereby permit the excess steam to rise to the atmosphere or other point of escape. In this manner the pressure within the heater can be automatically kept at the desired degree at all times.

- The construction shown in Fig. 3 is similar to that shown in Figs. 1 and 2, except that the inletconnection 6 is shown as also having an outlet opening 28,;which may be connected to a heating system or other apparatus using exhaust steam supplied by the same line as theheater. The opening 28 is controlled by a combined valve and oil separating plate 29, which is within the connecrugations or ribs on the valve member 9, namely, to enable said member to act more cliiciently as an oil separator. In order to prevent the passage of any objectionable 7 character wherebythe steam is purified of. V V scribed. i

amount of steam underneath the valve mem ber 29 and therebv carrv water into the u heating system or other apparatus, I provide suitable means, such as the guard or baffle Jlate 33. This ruard or ba'tlie alate is y l a 1 provided with one or more openingsor per-' fora'ti'ons 34 to permit water to pass there throu h and thence to the drain pipe 3.5. In this form of my invention, it will be noted that the relief valve 17 is common to both the heater and to the heating system or other piece of apparatus; and that, therefore, the pressure in both the heater and the heating system will be simultaneously automatically controlled by the operation of said valve. The valve members and 29 being independently operable, steam can at any time be entirely cut oil from either the heater or heating system or from both, as may be desired, thus giving complete 0011-. trol.

The described apparatus is. extremely simple and compact in itseonstruction, all the control parts being combined in one structure and operable from substantially the same point. I thereby eliminate the use of the complicated connections and pipes -tormerly employed for regulating the amount of steaingoing respectively into the heater and into the heating system. I also,

provide means of very simple and effective all entrained oil. I do not, however, Wish to limit myself to the exact construction and f opening, a' combined valve and separator plate for controlling said opening, and w ;meansfor automatically preventing the pressure from exceeding I a predetermined.

arrangement of the several parts which I have herein shown and described, as it will be obvious that the invention is applicable to heaters differing specifically in character from the one herein shown; and that various changes can be made in the details of the 1 parts without departing from the spirit and scope of my invention as set forth in the I appended claims.
